dt-bindings: mfd: syscon: Add missing simple syscon compatibles

Add various "simple" syscon compatibles which were undocumented or
still documented with old text bindings.

apm,xgene-csw, apm,xgene-efuse, apm,xgene-mcb, apm,xgene-rb,
fsl,ls1088a-reset, marvell,armada-3700-cpu-misc,
mediatek,mt2712-pctl-a-syscfg, mediatek,mt6397-pctl-pmic-syscfg, and
mediatek,mt8173-pctl-a-syscfg were all undocumented, but are in use
already. Remove the old text binding docs for the others.

Documentation/devicetree/bindings/arm/altera/socfpga-sdram-controller.txt

-Altera SOCFPGA SDRAM Controller
-
-Required properties:
-- compatible : Should contain "altr,sdr-ctl" and "syscon".
-  syscon is required by the Altera SOCFPGA SDRAM EDAC.
-- reg : Should contain 1 register range (address and length)
-
-Example:
-	sdr: sdr@ffc25000 {
-		compatible = "altr,sdr-ctl", "syscon";
-		reg = <0xffc25000 0x1000>;
-	};

Documentation/devicetree/bindings/arm/apm/scu.txt

-APM X-GENE SoC series SCU Registers
-
-This system clock unit contain various register that control block resets,
-clock enable/disables, clock divisors and other deepsleep registers.
-
-Properties:
- - compatible : should contain two values. First value must be:
-		   - "apm,xgene-scu"
-		second value must be always "syscon".
-
- - reg : offset and length of the register set.
-
-Example :
-	scu: system-clk-controller@17000000 {
-		compatible = "apm,xgene-scu","syscon";
-		reg = <0x0 0x17000000 0x0 0x400>;
-	};

-Power management
-----------------
-
-For power management (particularly DVFS and AVS), the North Bridge
-Power Management component is needed:
-
-Required properties:
-- compatible     : should contain "marvell,armada-3700-nb-pm", "syscon";
-- reg            : the register start and length for the North Bridge
-		    Power Management
-
-Example:
-
-nb_pm: syscon@14000 {
-	compatible = "marvell,armada-3700-nb-pm", "syscon";
-	reg = <0x14000 0x60>;
-}
-
-AVS
----
-
-For AVS an other component is needed:
-
-Required properties:
-- compatible     : should contain "marvell,armada-3700-avs", "syscon";
-- reg            : the register start and length for the AVS
-
-Example:
-avs: avs@11500 {
-	compatible = "marvell,armada-3700-avs", "syscon";
-	reg = <0x11500 0x40>;

Documentation/devicetree/bindings/mfd/brcm,iproc-cdru.txt

-Broadcom iProc Chip Device Resource Unit (CDRU)
-
-Various Broadcom iProc SoCs have a set of registers that provide various
-chip specific device and resource configurations. This node allows access to
-these CDRU registers via syscon.
-
-Required properties:
-- compatible: should contain:
-		"brcm,sr-cdru", "syscon" for Stingray
-- reg: base address and range of the CDRU registers
-
-Example:
-	cdru: syscon@6641d000 {
-		compatible = "brcm,sr-cdru", "syscon";
-		reg = <0 0x6641d000 0 0x400>;

Documentation/devicetree/bindings/mfd/brcm,iproc-mhb.txt

-Broadcom iProc Multi Host Bridge (MHB)
-
-Certain Broadcom iProc SoCs have a multi host bridge (MHB) block that controls
-the connection and configuration of 1) internal PCIe serdes; 2) PCIe endpoint
-interface; 3) access to the Nitro (network processing) engine
-
-This node allows access to these MHB registers via syscon.
-
-Required properties:
-- compatible: should contain:
-		"brcm,sr-mhb", "syscon" for Stingray
-- reg: base address and range of the MHB registers
-
-Example:
-	mhb: syscon@60401000 {
-		compatible = "brcm,sr-mhb", "syscon";
-		reg = <0 0x60401000 0 0x38c>;
